Let, number of spiders = x
number of insects = y
6x + 8y = 36
remember, legs can't be in fraction or decimal.
So, only (3, 2) fits with that.
So, there are 3 spiders & 2 insects in his collection.
Hope this helps!
Let's call trade balance b, exports e and imports i.
We now construct formula.
Put in the data from last year.
U.S trade balance for that year is -690 billion dollars.
To find out, graph them, analyze, and check.
Graph them.
You get the graph below.
Check the answers.
It looks like B matches.
So, the answer is B.
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.
Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.
So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)
If you need help solving or have any questions let me know!
24- 1,2,3,4,6,8,12,24
64-1,2,4,8,16,32,64
88-1,2,4,8,11,22,44,88
Here are all the factors.^^
The common factors are 1,2,3,4,6
